Posts and the root-filled tooth [PDF]
British Dental Journal, 2005 It is clear that teeth often require significant reconstruction following root canal treatment. It is also evident that there is an enormous variety of ways that can be used to achieve this. Although there is some debate about the relative contributions of the root filling and coronal restoration to endodontic success, it is agreed that the best ...

TOOTH ROOT BENDING STRESS CORRECTION ALGORITHM BASED ON VARIABLE PRESSURE ANGLE HOB (MT)
Jixie qiangdu, 2023 In order to solve the problem that the national standard cannot accurately calculate the bending stress of cylindrical helical gear with variable pressure Angle hob, a modified algorithm for calculating the bending stress of gear with variable pressure ...

Mandibular Teeth Movement Variations in Tipping Scenario: A Finite Element Study on Several Patients [PDF]
arXiv, 2020 Previous studies on computational modeling of tooth movement in orthodontic treatments are limited to a single model and fail in generalizing the simulation results to other patients. To this end, we consider multiple patients and focus on tooth movement variations under the identical load and boundary conditions both for intra- and inter-patient ...

Developing a Novel Approach for Periapical Dental Radiographs Segmentation [PDF]
arXiv, 2021 Image processing techniques has been widely used in dental researches such as human identification and forensic dentistry, teeth numbering, dental carries detection and periodontal disease analysis. One of the most challenging parts in dental imaging is teeth segmentation and how to separate them from each other.

Sharp Curvature of Premolar Resulting in External Apical Root Resorption of the Neighbouring Molar
Case Reports in Dentistry, 2011 This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second

Dense Representative Tooth Landmark/axis Detection Network on 3D Model [PDF]
arXiv, 2021 Artificial intelligence (AI) technology is increasingly used for digital orthodontics, but one of the challenges is to automatically and accurately detect tooth landmarks and axes. This is partly because of sophisticated geometric definitions of them, and partly due to large variations among individual tooth and across different types of tooth. As such,

Tooth-shaped plasmonic waveguide filters with nanometeric sizes [PDF]
Opt. Lett. 33, 2874-2876 (2008), 2009 A novel nanometeric plasmonic filter in a tooth-shaped Metal-Insulator-Metal waveguide is proposed and demonstrated numerically. An analytic model based on the scattering matrix method is given. The result reveals that the single tooth-shaped filter has a wavelength filtering characteristic and an ultra-compact size in the length of a few hundred ...

DArch: Dental Arch Prior-assisted 3D Tooth Instance Segmentation [PDF]
arXiv, 2022 Automatic tooth instance segmentation on 3D dental models is a fundamental task for computer-aided orthodontic treatments. Existing learning-based methods rely heavily on expensive point-wise annotations. To alleviate this problem, we are the first to explore a low-cost annotation way for 3D tooth instance segmentation, i.e., labeling all tooth ...

Multiple Idiopathic Cervical Root Resorption: A Challenge for a Transdisciplinary Medical-Dental Team [PDF]
arXiv, 2021 While tooth root resorption is a normal physiological process required for resorption and exfoliation of primary teeth, root resorption of adult teeth is largely pathological. This perspective focuses on multiple idiopathic cervical root resorption (MICRR), an aggressive form of external root resorption that occurs near the cemento-enamel junction (CEJ)
